A non-cancelable notification changes to cancelable notification and that happens or in the Advanced Editor and not in the wallpaper or the opposite. Tested with YouTube Vanced latest non-root version. To reproduce it open a playlist and press home (from the nav bar) and next/previous a video and the notification will be converted however the icon will not show up. I know this is a YouTube Vanced issue but it's also a Kustom issue (I think) because it can't detect the notification change.
